TL;DR: A polyamideimide and polyamide amic acid resin polymer that allows for reduced levels of toxicity in manufacturing is presented in this article, where a coating composition comprises at least one polyamide-imide resin, at least an aprotic dialkylamide solvent and at least a co-solvent.
Abstract: A polyamideimide and polyamide amic acid resin polymer that allows for reduced levels of toxicity in manufacturing. In an embodiment, a coating composition comprises at least one polyamideimide resin, at least one aprotic dialkylamide solvent and at least one co-solvent. In another embodiment, the at least one co-solvent is selected from a group consisting of methyl actetate, n-propyl acetate, t-butyl acetate, iso-butyl acetate, ethyl acetate, isopropyl acetate, methyl lactate, ethyl lactate, n-propyl lactate, isopropyl lactate, n-butyl lactate, isobutyl lactate, t-butyl lactate, cyclohexanone, cyclopentanone, n-butyl acetate, methyl alcohol, ethyl alcohol, isopropyl alcohol, n-acetyl morpholine, ?-caprolactone and methylcyclohexane.

TL;DR: In this article, the authors investigated the effect of Cr addition on the performance of the Mo/HZSM-5 catalyst and found that much higher methane conversion was obtained over Mo-Cr/HzSM-1 catalyst than over Mo/CZSM5 catalyst.
Abstract: The promotional effect of Cr addition on the methane aromatization performance of the Mo/HZSM-5 catalyst was investigated. It was found that much higher methane conversion was obtained over Mo–Cr/HZSM-5 catalyst than over Mo/HZSM-5. The results indicate that when the Cr/Mo molar ratio is 0.07, the methane conversion and aromatics selectivity reach 11.6 and 97.3% respectively at a reaction temperature of 973 K. Raising the temperature is beneficial to the methane conversion and 15.82% conversion is obtained at 1023 K. Modern measurements such as isopropyl alcohol decomposition and temperature desorption of ammonia (NH3-TPD) were used to characterized the catalysts. The results of isopropyl alcohol decomposition show that the surface acidity of Mo–Cr/HZSM-5 is increased at high temperature. The NH3-TPD findings imply that the Mo–Cr/HZSM-5 catalyst has much stronger acidity and more acid sites than Mo/HZSM-5, most likely one of the reasons for the enhanced activity for methane aromatization using Mo–Cr/HZSM-5 catalyst.

TL;DR: The majority of certain compounds tried, particularly isopropyl alcohol, were found to raise considerably the threshold for electrical convulsions in rats, and the possible significance of the isOPropyl group for benefits from ketogenic agents in epilepsy and for developing new or improving old antiepileptic agents is discussed.
Abstract: SummaryThe majority of certain compounds tried, and related in chemical structure to acetone, particularly isopropyl alcohol, were found to raise considerably the threshold for electrical convulsions in rats. Isopropyl alcohol increased the cortical depressant efficiency of diphenylhydantoin without demonstrable motor depression or narcosis. Some other alcohols and certain sugars and organic acids were ineffective. The possible significance of the isopropyl group (or isopropanol) for benefits from ketogenic agents in epilepsy and for developing new or improving old antiepileptic agents is discussed.

21 Mar 2003TL;DR: In this article, the use of green solvents such as ethanol, ethanol/water, isopropyl alcohol, isoamyl alcohol or ethyl acetate to extract phytosterols from wet corn fiber was described.
Abstract: The present invention relates to the use of “green” or relatively benign solvents such as ethanol, ethanol/water, isopropyl alcohol, isopropyl alcohol/water, ethyl lactate, acetone, butanol, isoamyl alcohol, or ethyl acetate to extract phytosterols from wet corn fiber. The resulting oil product contains free phytosterols and free fatty acids.
